The synthesis of vitamin E oleate by using vitamin E and oleic acid was studied.

以维生素E及油酸为原料，乙酸酐为共反应剂，三乙胺为催化剂合成了维生素E 油酸酯。

Three hundred and twenty-four crossbred (Landrace×Yorkshine) barrows with average body weight of 27 kg were randomly assigned to 6 dietary groups: group Ⅰ(chlorotetracycline group, added 50 mg/kg chlortetracycline in basal diet); group Ⅱ(origanum oil group, added 20 mg/kg oreganum oil in basal diet); group Ⅲ(probiotics group, added 1.5 g/kg probiotics in basal diet); group Ⅳ(nutrient enhancement group, elevated dietary vitamin E, vitamin B family and micro elements Zn, Mn, I); group Ⅴ(origanum oil+nutrient enhancement group); group Ⅵ(probiotics+nutrient enhancement group).

试验选用平均体重27 kg，健康长×大杂交阉公猪324头，随机分为6组：Ⅰ组（金霉素组，在基础日粮中添加50 mg/kg金霉素）、Ⅱ组（牛至油组，在基础日粮中添加20 mg/kg牛至油）、Ⅲ组（益生素组，在基础日粮中添加1.5 g/kg益生素）、Ⅳ组（营养调控组，提高日粮中维生素E和B族维生素、微量元素Zn、Mn和I水平）、Ⅴ组、Ⅵ组。

Ultraviolet light is needed to activate production of vitamin D in the body, which prevents rickets, osteomalacia and osteoporosis.

在人体内部，紫外线被用来刺激维生素D的生成，这种维生素能预防驼背、骨软化和骨质疏松症等骨骼问题。

Ultraiolet light is needed to actiate production of itamin D in the body, which preents rickets, osteomalacia and osteoporosis.

在人体内部，紫外线被用来刺激维生素D的生成，这种维生素能预防驼背、骨软化和骨质疏松症等骨骼问题。

The additional supplements including glucose,ascorbic acid and insulin had the enhancement effects on C.andersoni development,while folic acid had no significantly effect on C. andersoni development and calcium pantothenate had inhibited effect.When added 50 mmol/L glucose,50μg/ml ascorbic acid,0.3 U/ml insulin into 10%FCS RPMI-1640 medium,the proliferation of C.andersoni had a great significantly increase,and the gene copies of C.andersoni were 8-fold compared with that in 10%FCS RPMI-1640 medium.

冻融法+蛋白酶K法+声裂法提纯隐孢子虫卵囊DNA效果最佳，其次为冻融法+声裂法和蛋白酶K法+声裂法，冻融法+蛋白酶K法效果最差。10%FCS是培养安氏隐孢子虫的最佳FCS浓度，葡萄糖、维生素C和胰岛素都具有促安氏隐孢子虫增殖作用，泛酸钙无促虫体增殖效果，而叶酸则抑制虫体增殖。10%FCS RPMI-1640培养液中加入50 mmol/L葡萄糖，50μg/ml维生素C和0.3 U/ml胰岛素促安氏隐孢子虫增殖效果最显著，虫体增殖8倍。

Itamin B5 or pantothenic acid is a water-soluble vitamin that helps in the production of energy.

维生素B5或泛酸是一种水溶性维生素，可帮助生产的能源。

The B group of vitamins includes B1, B2, B3, B6, B12, folic acid, biotin and pantothenic acid.

B组的维生素包括B1中，素B2 ， B3中， B6中，维生素B12 ，叶酸，生物素和泛酸。

Honey is a great source of vitamins and minerals, such as vitamin B6, thiamin, niacin, riboflavin and pantothenic acid.

蜂蜜是维生素B6、维生素B1、烟酸、核黄素及泛酸等维他命和矿物质的巨大来源。

Intrinsic factor is a natural substance present in the stomach and is essential to the digestion of vitamin B12; being without it leads to pernicious anemia and vitamin B12 deficiency.

内因子是一种存在于胃的天然物质，是维生素B12吸收所必不可少的；如果内因子缺乏，就会导致恶性贫血与维生素B12缺乏。

These experimental results demonstrated that photosensitization was the potential mechanism of photoinduced toxicity of 1-amino-2,4-dibromoanthraquinone to D.magna.

此外，添加抗氧化剂(维生素C、维生素E和β-胡萝卜素)可以显著减弱1-氨基-2，4-二溴蒽醌对大型溞的光致毒性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
